Shrubs, erect; not rhizomatous. Stems 10–30 dm; distal branches arching, bark dark brownish red; infrastipular prickles single or paired, curved, falcate, 6–12 × 3–7 mm, lengths varying or ± uniform, internodal prickles sometimes mixed with aciculi and glandular-setae. Leaves persistent, 4–6.5 cm; stipules 6–10 × 2–4 mm, auricles 3–5 mm, margins stipitate-glandular, surfaces glabrous, eglandular; petiole and rachis with pricklets, puberulent, stipitate-glandular; leaflets 5–7 (–9), viscid glands with ripe apple scent, terminal: petiolule 5–10 mm, blade mostly suborbiculate or broadly oval, 10–25 × 8–15 mm, base obtuse, margins 2-serrate or multi-serrate, teeth 10–18 per side, apex acute to obtuse, abaxial surfaces glabrous or pubescent, usually densely viscid-glandular, adaxial green, lustrous to dull, puberulent or glabrous. Inflorescences panicles, 1–3 (–7) -flowered. Pedicels erect, 6–9 mm, densely stipitate-glandular, sometimes mixed with aciculi [and setae]; bracts 2, ovatelanceolate to lanceolate, 15 × 5 mm, margins stipitate-glandular, surfaces glabrous, eglandular. Flowers 2–4 cm diam.; hypanthium obovoid or broadly oblong, 5–6 × 3–4 mm, eglandular, neck (0–) 1–1.5 × 3–4 mm; sepals erect or spreading, rarely reflexed, lanceolate or ovatelanceolate, 14–18 × 2 mm, margins mostly pinnatifid, tip 3–5 × 0.5–1 mm, abaxially densely stipitate-glandular; petals bright or deep pink, 11–20 × 11–18 mm; carpels 25–45, styles villous or glabrous, exsert 1–2 mm beyond stylar orifice (1.2–2 mm diam.) of hypanthial disc (2.5–4 mm diam.). Hips dark red, subglobose to broadly ovoid, ellipsoid, or pyriform, 10–25 × 7–22 mm, glabrous, sometimes setose, eglandular; sepals tardily deciduous, mostly erect. Achenes 15–25, tan, 3.5–4 (–5) × 2–2.5 (–3) mm. 2n = 35, 42.

Discussion

Varieties 2 (2 in the flora).

Rosa rubiginosa has been introduced throughout Canada and the United States except the desert southwest. Plants are compact, upright shrubs without rhizomes. Stems have stout, falcate infrastipular prickles mixed with internodal prickles, aciculi, and glandular setae. Leaflet blades are densely viscid-glandular with ripe apple scent and margins 2- or multi-serrate with stipitate glands.

Rosa eglanteria Linnaeus is a formally rejected name that pertains here.
